Makeup artist Lauren Cosenza shows us how to mirror these mermaid-inspired eyes.

1. Highlight. With your foundation already applied and a wash of light pink blush swept over your cheekbones, reach for a loose pigment like MAC Pigment in Blonde's Gold" — like our model Kelly Thomas used here. "Then, pat the shimmering color onto your brow bone with a flat eyeshadow brush, and into the inner corner of the eye with a domed eyeshadow brush," says Cosenza.

2. Go green. "Apply the first of three shadows to the inner corner of your eye, using MAC Pigment in Emerald Green and applying it with the Lancôme Rounded Eyeshadow Brush in #23," she says. "This brush will help give you that ombré effect as you layer on each color. But with these green pigments, sweep them on only from the inner corner of your eye toward the center, staying below the crease."

3. Turn to teal. "Tissue off the slanted eyeshadow brush and dip the tip into the MAC Pigment in Teal," Cosenza says. "Then, press the color gently onto the center of your eye, brushing it toward the outer corner."

4. Be bold with blue. "Again, tissue off the eyeshadow brush to remove any green or teal residue, and using MAC Pigments in Naval Blue, apply the blue shadow to the outer corner of your eye, angling the brush to create that subtle smoky eye look," she says.

6. Trace your upper lash line. "Beginning at the outer corner of your lower lash line, run Clinique Quickliner For Eyes in Intense Midnight below the lower lashline to the midway point, and then blend the teal and navy liner shades where they meet in the center," she says. "Then, line the outer corner of your upper lash line only with the navy liner to add more definition."

8. Wear the heck out of this look like the gorgeous mermaid you are! For a more intense eye, instead of keeping the eyeshadow colors below the crease of your eye, bring them up closer to the brow bone for a more dramatic, Halloween-appropriate effect.
